Comment Say goodbye to wireless microphones (Score 1) 68
Most wireless microphones operate in the "white space" frequency ranges. The FCC pushed wireless users out of the 698-806 MHz a couple years ago and caused havoc in the theater and concert industries - the small theater I worked for spent over thirty thousand dollars replacing their wireless mics, because it is now illegal to buy, sell, or use a 700 MHz microphone.
I can't imagine what it will be like if they take away all the spectrum. It's hard enough as is to do frequency coordination for twenty or thirty mics that are used in larger productions.
